Hi Graham I love your completely new definition of a software calculator. Never seen anything like that before, especially the ability to save formulas so you can tweak and improve in the future. Genius. I wish you success with it. Cheers Nick :o)

I was AND will continue using FC Calculator to estimate all my website projects.It works fantastically well as I can tweak different set of formulas to identify how much it takes to complete a project with X number of developers/designers. Keep up the great work!

It's a calculator Jim, but not as we know it!
